# SUPPLEMENTARY INFORMATION:

                    In the                     **Federal Register**                     of December 22, 2023, FDA published a notice of availability for a draft guidance entitled, “Master Protocols for Drug and Biological Product Development.” This action opened a docket with a 60-day comment period. The Agency received requests for an extension of the comment period for the draft guidance. After considering the requests, and in light of the fact that the original comment period is scheduled to close on February 20, 2024, FDA has decided to extend the comment period for 30 days, until March 21, 2024. The Agency believes that this extension allows adequate time for interested persons to submit comments to ensure that FDA can consider the comments before it begins work on the final version of the guidance.                

Dated: February 13, 2024.

Associate Commissioner for Policy.
